SERVOPRO MultiExact 4100
Servomex has decades of experience in
supplying the gas analysis technologies
needed to control processes, guarantee
product purity and ensure plant safety.
With the long-serving SERVOPRO 4100
multi-gas analyzer reaching the end of
its life, the advanced SERVOPRO
MultiExact 4100 has picked up the baton
to continue the tradition of accuracy
and dependability.
A digital multi-gas analyzer, the MultiExact
4100 can be configured with up to four
of Servomex’s world-leading sensors for
simultaneous gas measurements, including
oxygen, nitrogen, methane, nitrous oxide,
carbon monoxide, argon, helium and
carbon dioxide.
This also makes it simple to duplicate
analyzer configurations using a
thumb drive.
SENSING TECHNOLOGIES:
The MultiExact 4100 is backwards
compatible with many current
installations, including the legacy 4100,
and complies with existing standards and
agreements. This makes it easy to upgrade
and achieve the high-performance
measurement stability and advanced
digital communications capabilities of a
modern analyzer platform.
It also offers built-in support for Servomex's
AquaXact 1688 moisture transmitter,
allowing touchscreen control and easy
field replacement of the Aluminum Oxide
ultra-thin film sensor tip.
Low cost of ownership is delivered
through Servomex’s ultra-stable, non-
depleting digital sensing technologies,
which help extend maintenance intervals.
An independent auto-calibration
function helps to keep operational and
maintenance expenses to a minimum. This also provides a connected AquaXact
1688 with access to the MultiExact 4100’s
32 alarms, 32 relays and full range of
analog and digital communications,
including 0-10V DC, 4-20mA, RS232,
RS485, serial Modbus, Ethernet Modbus
TCP/IP and PROFIBUS.
An intuitive, icon-driven color touchscreen
makes it easy to interact with the
MultiExact 4100. The device also has a
USB serial port to allow data logging and
software upgrades. The flexibility of the MultiExact 4100
means it is suitable for a wide range
of applications, including monitoring
combustion processes using oxygen
enrichment – see page 06.
That makes it more important than
ever before to upgrade any existing
1900A/1900B installations to the much
more advanced SERVOTOUGH Oxy 1900
digital analyzer.

Spares support for the analog legacy
version of Servomex’s hazardous area
Paramagnetic oxygen (O 2 ) analyzer, the
1900A/1900B, has now come to an end.
The Oxy 1900 was specifically designed
to match or exceed its predecessor in
every department, and has delivered
proven reliability to processes around
the world for several years, providing the
compliances and features that modern
engineers expect.
It sets the highest standards for accurate,
reliable O 2 analysis in challenging
industrial conditions, providing significant
improvements over competing hazardous
area O 2 analyzers.
A digital, microprocessor-based analyzer,
the Oxy 1900 uses Servomex’s trusted
Paramagnetic O 2 sensing technology.
This ensures fully up-to-date O 2 analysis,
meeting current process demands for
even the most demanding applications.
The Oxy 1900 provides efficient, complete
sample heating for greater measurement
stability, and advanced software that
enables the analyzer to self-diagnose
faults and issues.
It also has a unique Flowcube sensor to
guarantee low-flow indication during
normal operation, and an integrated
pressure compensation system to enable
tighter process control if the sample
pressure varies.
Options available include an innovative
heated sample bulkhead, which eliminates
the need for a sample conditioning system
on samples with a dew point up to 50 o C
(122 o F). Sample system failure is the
cause of around 80% of all Paramagnetic
replacements, so this provides peace of
mind by maintaining the process fluid in
its gas phase, minimizing analyzer damage
from sample compensation.
APPLICATIONS INCLUDE:
Process control
Safety critical oxidation
(such as ethylene oxide and propylene oxide purity)
Feedstock clean-up
Inerting/blanketing
Flare stack analysis
Vapor recovery
Delivering trusted reliability in hazardous
areas, the Oxy 1900 is certified for ATEX Cat
2, IECEx Zone 1 and CSA Class 1, Div 1, and
complies with Safety Integrity Level (SIL) 2.
Using an improved temperature
coefficient, it is ideal for regions of the
world with variable weather conditions
and extreme temperature swings, such as
the Middle East and Asia.
